17、he International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical a
18、nd electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical c
19、ommittees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organizatio
20、n for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical commi
21、ttee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is
22、 accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and r
23、egional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in confo
24、rmity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for an
25、y personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normati
26、ve references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsi
27、ble for identifying any or all such patent rights. International Standard IEC 61047 has been prepared by subcommittee 34C: Auxiliaries for lamps, of IEC technical committee 34: Lamps and related equipment. This second edition of IEC 61047 cancels and replaces the first edition published in 1991, its
28、 Amendment 1 (1996) and Amendment 2 (2001). This second edition constitutes a technical revision. The first edition needed to be revised completely after the decision to delete all EMC-related requirements, given that EMC varies from region to region.

29、proved subscription and freemailing clients of the SABS.61047 IEC:2004 7 The text of this standard is based on the following documents: FDIS Report on voting 34C/635/FDIS 34C/643/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in th
30、e above table. This standard is to be read in conjunction with IEC 61347-1 and IEC 61347-2-2. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. In this standard, the following print types are used: requirements proper: in roman type; test specifications: in italic
31、type; notes: in smaller roman type. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will
32、be reconfirmed; withdrawn; replaced by a revised edition, or amended. This standard may only be used and printed by approved subscription and freemailing clients of the SABS.61047 IEC:2004 9 INTRODUCTION This International Standard covers performance requirements for electronic step-down convertors
33、for d.c. supplies up to 250 V and a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, operating with controlled voltage filament lamps at frequencies deviating from the supply frequency. Attention is drawn to the fact that operating frequencies below 20 kHz may cause audio noise. NOTE CISPR requirements
34、regarding radio interference have to be observed in some countries. In order to obtain satisfactory performance of filament lamps and electronic convertors, it is necessary that certain features of their designs be properly coordinated.

36、e This International Standard specifies performance requirements for electronic step-down convertors for use on d.c. supplies up to 250 V and a.c. supplies up to 1 000 V at 50 Hz or 60 Hz with operating frequencies deviating from the supply frequency, associated with tungsten halogen lamps as specif
37、ied in IEC 60357 and other filament lamps. NOTE 1 The tests in this standard are type tests. Requirements for testing individual convertors during production are not included. NOTE 2 Requirements for convertors which incorporate means for varying the lamp power are under consideration. NOTE 3 It may
38、 be expected that convertors complying with this standard will ensure satisfactory operation between 92 % and 106 % of rated supply voltage of filament lamps with rated lives greater than 200 h and rated voltage less than 50 V. NOTE 4 There exist regional standards regarding the regulation of mains
39、current harmonics for end-products such as luminaires and independent control gear. In a luminaire, the control gear is dominant in this respect. Control gear, together with other components, should comply with these standards. 2 Normative references The following referenced documents are indispensa

NOTE 2 The value of the power factor takes into account the effect of the distortion of the current waveform. 3.4 high audio-frequency impedance convertor a convertor the impedance of which in the frequency range 250 Hz to 2 000 Hz exceeds the values specified in Clause 11 3.5 short-circuit proo

NOTE The requirements and tolerances permitted
46、by this standard are based on testing of a type test sample submitted by the manufacturer for that purpose. In principle this type test sample should consist of units having characteristics typical of the manufacturers production and be as close to the production centre point values as possible. It
47、may be expected with the tolerances given in the standard that products manufactured in accordance with the type test sample will comply with the standard for the majority of the production. Due to the production spread however, it is inevitable that there will sometimes be products outside the spec
48、ified tolerances. For guidance of sampling plans and procedures for inspection by attributes, see IEC 60410. 4.2 For tests which are carried out with a lamp or lamps, this lamp(s) shall fulfill the following requirements. The wattage of the lamp(s) when measured at its rated lamp voltage (d.c. or a.
49、c. 50 Hz/60 Hz) shall not differ from the rated wattage by more than 6 0 +%. 4.3 The tests shall be carried out in the order of the clauses, unless otherwise specified. 4.4 One specimen shall be submitted to all the tests. 4.5 In general all the tests are made on each type of convertor or, where a range of similar convertors is involved for each rated wattage in the range or on a representative selection from the range as a
